Furthermore, the chaplet is not will be apparent to those skilled in this art limited as to distance between the core and as the invention becomes better understood mold-engaging portions because by cutting by reference to the following description out a piece of the body part transversely when considered in connection with the acfrom side to side thereof to form the vent companying drawings, in which opening 11 the bridgepieces may be drawn 90 5 Figure 1, is a vertical section through a or pressed out to any depth within reasonmold showing a number of chaplets embodyable limits, whereas in previous construcing my invention, holding a core in position; tions the depth was limited by a draw of Fig. 2, is an enlarged end elevation of a the metal.
